Ztylus

• The Ztylus Revolver M Series case for the iPhone X
  features a revolving wheel on the back containing six built
  in-lenses.
• You can rotate the wheel to select the lens you want,
  then place it right in front of the phone’s camera
  lens. 
• The case comes with macro/super macro,
  fisheye/telephoto, and wide/telephoto lens
  pairs. 
• It costs $34.95, and is available on
  Amazon. 

Sometimes your phone’s camera lens isn’t enough for the type of
pictures you want to snap — whether it’s wide-angle fisheye shots
or bigger zooms than what the phone is capable of. 

There are plenty of external lenses available for mobile
photography, but they can easily get expensive, and they usually
require the user to carry around different lenses that need to be
swapped out. The
Ztylus Revolver M Series case for the iPhone X offers an
all-in-one package of six lenses, at $35. 

The case has a revolving wheel on the back, which contains 3
pairs of lenses: macro/super macro, fisheye/telephoto, and
wide/telephoto. Instead of removing a lens and replacing it with
another, you can simply rotate the wheel and extend the external
lens to the phone’s existing lens. 

The rotating wheel is magnetic and removable, so you don’t need
to have unnecessary extra bulk if you won’t be using the
lenses.  Because the lenses are stored inside the wheel, you
also won’t need lens caps to protect the glass. However, as
mobile phones weren’t necessarily intended to be used with
external lenses, some image distortion can be expected. 

The M Series case comes in 16 color options, and is
available on Amazon.
